TWINE-SAVING ATTACHMENT FOR THRESHING-MACHINES.

To all whom it may concern 'Be it known that I, JOSEPH A. Raarsnr, a citizen ofthe United States, and a resident of Beatrice and county of Gage, State of Nebraska, have made an Improvement in Twine-Saving Attachments for Threshing- Machines, of which the following is a speci-'' .fication; My lnventlon 1s an apparatus forremow mg twine from bundles of grain while being fed to a threshing. cylinder. In practice, it

is located directly in front the toothed cylinder and concave where the retarder l is ordinarily located in threshing-machines of the latest type. In other words, it is located between the band or twine cutters and the threshing cylinder, "and below their plane, so thatthe grain bundles slide over it on their way to the cylinder. In such'pasan enlarged cross section on line 3'3 of Fig. 1. Fig. 4 is a perspective view of one of the twine-removing teeth or fingers, to-

gether with its retracting spring and the holder to which the finger is pivoted. Fig. 5 is a cross section on the line 5-5 of Fig. 4:. Fig. 6 is a plan view of a portion of the top of the slotted guard constituting part of the separator or twine-saver.

The two most prominent features of th apparatus are the teeth or fingers 1, and the slotted guard 2. The fingers are pivoted to holders mounted on, and revolving with, the horizontal shaft 3, and the slotted guard is held in bent or curved form between parallel vertical plates 4=-4 in which the shaft 3 has its bearing. A fly-wheel 3 is mounted on the shaft 3 and the latter may be' driven by a suitable gear-which it is unnecessary to describe.

The guard 52 may be producedeconomically by stamping it out of a sheet of steel, or it may be produced from a steel plateby milling the slots therein. The plate thus Specification of Letters Patent.

slotted is then bent into the form shown in Figs. 1 and 6, where the upper portion of the guard 1s nearly horizontal, and its upper end is attached to a transverse rod or bar 5 that extends'through and is bolted to the plates w Thelower end of the guard is attached to a bar 6 which extends through arc-slots 7 and is provided with nuts 8, as shown Figs. land 2, for clamping the rod 1n any adjustment. It is obvious that this construction and arrangement permit the guard to be adjusted sothat its top portion will be nearer to or farther from the horizontal and that its curvature may thus have a greater or less radius relative to the teeth or fingers 1, so'that the latter will enter the grain'bundles a greater or less depth.

The teeth or fingers 1 are pivoted at 9 (see Fig. 4:) to plate disks 10, which are provided with peripheral notches adjacent to the teeth. These disks 10 are in turn riveted to cast-metal plates 11 having radial fingers and a polygonal opening which adapts them to fit on the polygonal shaft 8. The disks 10 and plates 11 arefriveted together at'l2 adjacent to. the pivots of the fingers 1.

These two parts 10 and 11 thus constitute a rig d holder and support for the teeth 1. A spiral retracting spring 13 is provided for each tooth, the same extending across the notch in'the disk 10 which is adjacent to every tooth. The spring is attached to the tooth by means of a metal plate 14 (see especially Figs. 1 and 5.)

The operation of the apparatus is briefly described as follows :The grain bundles, passing from the cutters which have severed the twine previously binding them, slide over the top of the guard 2 in the direction of the arrow, Fig. 8, and the shaft 3, rotating in the same direction, carries fingers 1 around so that they sweep through the slots of the guard in its curved portion, and thus reach into the bundles and engage the twine and drawit down out of the'bundles until they strike the bar 15 (see Figs l and 6) which extends across the front of the guard and is secured thereto. In other words, the fingers gather the twine lengths and draw them out of the bundle and the twine is freed from the teeth by striking on the bar 15, and is then deposited in a box or receptacle provided for the purpose. The ends of the bars extend through slots 16 in the plate 4, which construction permits adjustment of the guard, as before described with reference to the bar 6 and arc slot 7 It will be understood that in this contact of the teeth with the bar 15. they are thrown back until they pass the same, which action is permitted by the springs 13 which subsequently retract them to the normal radial position.

The upper ends of the slots in the guard which are'adjacent to the upper bar 5 are somewhat enlarged or widened as indicated in Fig. 6, in order to afford passagefor the teeth or fingers 1, without binding, upon their entrance into the guard. It is apparcut that the bars 56 and 15 serve to connect and. braceapart the parallel end plates st. Between the series of teeth-or-fingerholders comprising parts 10 and '11, there are interposed sleeves l6, aswill be understood by reference to Figs. 2 and 3, said sleeves thus serving to hold the teeth-holders duly spaced apart.

l Vhat I claim is:- 1

l'. A twine-remover and saver comprising a slotted guard, a horizontal rotatable shaft extending beneath the top portion of said guard, and a series of springueti -acted fingers pivoted tosupports on the shaft and rotating with said shaft and projecting, in

a part of their revolution, through the slots 7 of the guard, as described. -1 A ine-remo e nd saver com risin a lot e gua d, a ont ro atab e haf copies ofth i s, patent may he obtained for fwe cents each, by addressingithe Commissioner of Ratentsf having means for-clamping it in j Witnesses extending beneath the top portion "ofsaid guard, a series of spring-retracted fingers pivoted to supports on the shaft and rotating with said shaft and projecting, in a art of their revolution, through the slots of the guard, and a contact bar applied to the lower portion of the guard for assisting in freeing twine from the fingers, as described.

J 3. In a twine-saver adapted for applica- .tion to threshing-machines, the combination with a horizontal shaft, and spring-retracted fingers applied thereto and adapted to rotate tl'ierewith, a slotted guard overwhich' the grain bundles pass, end plates to which the upper portion of the guard is secured, 1 i said plates being prov ded with arc-slots,

and the lower portion of the guard attached to a bar projecting through said, slots and quiredadjustment. r
